The Biological Importance of Water

Water is a polar molecule, which means it has beas of roughly and meagrely disal slump aras of charge. This is because of the electronegativity of hydrogen and of atomic number 8. negativism is the ability of an linage cell to attract electrons in a covalent bond. In water, oxygen has a much naughty electronegativity, so the shared electrons are attracted reasonably more towards the oxygen, do the oxygen slightly negative and the two hydrogens slightly positive. near water molecules are attracted to separately separate, forming hydrogen bonds between the slightly positive hydrogen and the lonely(prenominal) pairs of electrons from the oxygen. Hydrogen bonds are quite hygienic compared to other intermolecular forces, allowing the water to be very stable. This gives it a high change state heighten and a high SHC. Each water molecule has the potential to form four-spot hydrogen bonds which makes the boiling point much higher than other hydrogen bonded compounds. Water sticks to itself collectible to the polarity, and this is called cohesion. However, another property of it is esteem, which is ordinarily stronger than the cohesive forces. This is why it spreads unwrap on erupts like glass, as it is more attracted to that than itself. The polarity too allows water to act as a solvent, giving it the byname of the universal solvent.

These properties allow many another(prenominal) biological functions to ask place. In demonstrates, many molecules including hormones and sugars are transported in solutions. Cohesion and adhesion allow this to take place as the water st icks to itself and the walls of the tube, an! d its low viscosity allows it to flow through. Water is a good surround for chemical reactions such as photosynthesis and public discussion because of its thermal stability and solvent properties. It is also essential in keeping plant cells turgid, which is essential so the plant has a large surface area for photosynthesis. Water is also important in animals. entirely transport fluids such as blood and cytoplasm are water based, and...If you want to get a full essay, army it on our website: OrderCustomPaper.com
